reactjs - SyntaxError: Invalid or unexpected token @import

Question

I am trying to add Jest and Enzyme to a React webpack project.

Everything is working, until I add tests to a component, with a style sheet importing google fonts.

The error I get is:

● Test suite failed to run
    /Users/dev/Code/Git/react-redux-webpack/src/App.sass:1
    ({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,global,jest){@import url('https://fonts.googleapis.com/css?family=Barlow+Condensed')
                                                                                             ^
    SyntaxError: Invalid or unexpected token

The sass file looks like:

@import url('https://fonts.googleapis.com/css?family=Barlow+Condensed')

body
    background: #f9f9f9
    color: #444444
    font-family: 'Barlow Condensed', sans-serif
    text-align: center

.container
    width: 100%
    max-width: 960px
    margin: 0 auto

.container__logo--image
    position: absolute
    top: 50%
    left: 50%
    margin-left: -75px
    margin-top: -75px

My .babelrc:

{
  "presets": [
    "react",
    "stage-0",
    [
      "env",
      {
        "targets": {
          "node": "6.10",
          "browsers": ["last 2 versions", "safari >= 7"]
        }
      }
    ]
  ],
  "plugins": ["transform-class-properties"]
}

I have all the required loaders in webpack, I can build and serve the sass all day with no issues. It is the introduction of Jest I am struggling with.

I have pushed a branch with the current state of code here https://github.com/nombienombie/react-redux-webpack/tree/feature/jest-unit-tests

I added the following to my package.json:

  "jest": {
    "moduleNameMapper": {
      "\.(jpg|jpeg|png|gif|eot|otf|webp|svg|ttf|woff|woff2|mp4|webm|wav|mp3|m4a|aac|oga)$": "<rootDir>/__mocks__/fileMock.js",
      "\.(css|sass)$": "<rootDir>/__mocks__/styleMock.js"
    }
  },

and added the following in a mocks folder:

fileMock.js

module.exports = 'test-file-stub';

styleMock.js

module.exports = {}
